One more time for the incredibly and deliberately obtuse.
Libertarian Party Platform link:

The pertinent section copied and pasted:
1.3 Personal Relationships
Sexual orientation, preference, gender, or gender identity should have no impact on the
government's treatment of individuals, such as in current marriage, child custody, adoption,
immigration or military service laws.
Government does not have the authority to define, license or
restrict personal relationships. Consenting adults should be free to choose their own sexual practices
and personal relationships.
With the sentence you need to read a few times bolded. The libertarian party is against the government licensing your personal relationships, which is what we've told you several times. Any further argument of they are "for licensing etc." is deliberate ignorance. I can't do any better than this other than getting your mother to read you the sentence.
